Kutcher: 'I send Demi romantic tweets'

Ashton Kutcher has revealed that he enjoys sending romantic online messages to his wife Demi Moore.

The actor admitted that he posts messages to her on social networking sites like Twitter and Facebook so that she can be "publicly adored".

He wrote for Harper's Bazaar: "Sending sweet nothings on Twitter or Facebook is fun. In some ways, it's no different than sending flowers to the office - You are declaring your love for everyone to see. Who doesn't like to be publicly adored?"

However, the 32-year-old said that people should be careful of what they put online.

He explained: "Just remember that what you post is out there and there's some stuff you can't unsee."

Kutcher added that although he enjoys web interaction, it can never be a substitute for human contact.

He said: "When someone needs us, he or she needs all of us. There's no text that can replace a loving touch when someone we love is hurting."
